The pickling process removes the scale from the hot rolled steel surface by for applications that require a clean, uniform surface and good flatness. The pickling process removes scale from the hot rolled sheet surface by utilizing water and other inorganic solutions at the mill.

S235JR HR Coil Pickling and Oil Hot Rolled Steel Coil Thickness1.5mm~100mm Description: HRPO steel is still considered hot rolled steel even though it does not have any scale.The final product of HRPO steel is created when steel mills use acid baths to remove the scale that usually forms on the surface of carbon steel coil, as the coil is cooling.

The hot rolled steel H section based steel structure has reasonable and scientific structure, good plasticity and flexibility, and high structural stability. It is appropriate for the building structure bearing vibration and large impact load.
